- ONS-1001: Environmental data & analysis (20) This module, unlike most others, concentrates on giving the student the basic literature searching, numerical and statistical skills required for pursuing the rest of their respective programmes of study. The course relies heavily on computer-based material and so the student also learns how to use and evaluate on-line information, as well as how to converse, discuss and learn via the Blackboard software package. The course starts with an introduction to the Information Literacy Cycle, issues of plagiarism and how to avoid it, and good practice for citing and referencing. Thereafter, the course concentrates on key aspects of any science degree. Lectures introduced include: distributions of populations within scientific data; ideas of probability; unit systems used within science; accuracy and precision; algebraic manipulation; graphing linear systems; and coping with non-linearity in natural systems. Included as part of this will be an introduction to the use of excel and powerpoint - two software packages which are almost essential in the life of an undergraduate student. Following these mainly numerically-related lectures, the module focuses on the scientific method, hypothesis setting and testing; these leading to the fundamental ideas concerning experimental design. These concepts then extend to discussing the importance of replication in scientific datasets. Finally, an introduction to specific statistical tests (parametric and non-parametric) is presented. Library searching and referencing Introduction to distributions within scientific data Ideas of probability Description of distributions Preamble to MS Excel On-line exercises Presentation with MS Powerpoint Unit systems used in science Accuracy & precision. How many decimal places? Introduction to algebraic manipulation Graphing of linear systems Coping with non-linearity in nature (logs etc.) The scientific method: hypothesis setting and testing Introduction to experimental design The importance of replication in scientific datasets Examples of statistical tests: parametric versus non-parametric Regression and correlation ANOVAor
